Every year, AWS Principal Technologist Rick Houlihan leads this technical session dedicated to advanced users of Amazon DynamoDB. He explains design patterns and data models that are based on a collection of implementations and best practices used by a variety of customers to deliver highly scalable solutions for a range of business problems. In this first part of a two-part series, Rick discusses and demonstrates important concepts including partition sharding and index overloading, scalable graph processing, and managing distributed locks.

Here's a tip, set the playback speed to 0.9x. You're welcome.

He speaks like he is in a hurry...Does he understand that is important to digest the information? ... The objective is to teach the concepts not to reach a certain number of words per minute.

Slow down 🤣🤣

I love Rick. He is a horse-racing commentator equivalent of DynamoDB webinars.

@Chris-se3nc Год назад

Ah yes DynamoDB and Cassandra, the most difficult NoSQL db to model in. MongoDB for the win.

@treepiesinc1418 3 года назад

Very interesting but too fast... I came here to comment and saw another comment to playback with lower speed. That worked. Also ups and downs in tones would help.

@ningo5000 3 года назад

Thanks for your videos but it is a little bit fast

Just remember, it’s ok to breath between your thoughts and sentences; I think Rick only thinks in one complete thought with no breaths in between 😂

@karanmurthy1840 3 года назад

Can we use the GSI (demo1_s) to trigger the Lambda?

@rdeleonf 3 года назад

20:31 I understand getting all trades for securityID might work conceptually, but how would this work from a technical point of view, as querying over the partition key has to be specific? Are you suggesting parallel queries (for 0-100 range - 101 queries) ?

@edwardgonsalves4755 3 года назад

Yes. docs.aws.amazon.com/amazondynamodb/latest/developerguide/bp-partition-key-sharding.html

Great information but I would suggest to work on the presentation style. It is fairly monotone and it seems like you are just trying to talk as fast as possible without any breaks. Slow down and pause between sentences please and the information will come across much more easily.

@hugojeller 3 года назад

I don't disagree with you but he clearly knows his shit. I think he has so much to say that he's just going and going. Everything I watched from him was mind-blowing (for me at least)

@@dakinenz here's another: pause and go back haha

@dakinenz 3 года назад

@@hugojeller Yeah, but that means it's taking 2x longer to watch, rather than 1.1x longer :p (strangely, despite it sounding very fast, only reducing it to 0.9x playback it sounds like a normal pace)

@hugojeller 3 года назад

@@dakinenz I mean, there's no rush in learning, this is top content I wish I had access 3~4 years ago. DynamoDB opened the doors for a bunch of projects I thought were hard to maintain but in reality are not. They just require highly dynamic tables (NoSQL) or highly scalable infra (AWS), both I'm not confortable handling on my own. I always heard "NoSQL is probably not for you" but because of this video (and tons other now that my mind was blown) I realized that I NEEDED NoSQL in some projects. I rather take 10x longer to watch this video than not have it at all.
